Verified step by step guidance

1. Step 1: Understand the role of physical and mental abilities in the labor market. These abilities affect an individual's productivity, which influences the types of jobs they can perform and their efficiency in those jobs.
2. Step 2: Recognize that higher productivity often leads to access to better-paying jobs because employers are willing to pay more for workers who can produce more or higher-quality output.
3. Step 3: Analyze how differences in abilities create variation in productivity among individuals, which in turn leads to differences in wages and income levels.
4. Step 4: Connect this variation in income to the concept of income inequality, where individuals with higher abilities tend to earn more, contributing to disparities in income distribution.
5. Step 5: Conclude that income inequality arises partly because individuals differ in their physical and mental abilities, which affect their job opportunities and earnings, rather than all individuals earning the same or income being determined solely by external factors like government policies.
